摘要
芳香族化合物和氨衍生物可以防止纤维素降解。这类助剂用于次氮酸盐单段漂白中可以减少漂白时纤维素降解及提高漂白浆的强度。研究表明,这类助剂中以2,4,6-三叔丁基苯酚和防老剂D效果较好,漂白损失降低、白度提高、浆强度增加。
Aromatic compound and ammonium derivatives provide the possibility to prevent cellulose degradation.The use of this kind of additives in single stage hypochlorite bleaching may decrease,the cellulose degradation during bleaching, and increase the strength of bleached pulp.The results showed that among the additive used.Both 2,4,6 terbutyl phenol and antiager D have the better effects:bleaching loss diminished,whiteness improved and strength increased.
